Introduction to Java
Java is a high-level programming language initially created by Sun Microsystems and discharged in 1995. It is a broadly useful computer programming language that is simultaneous, class-based, object-oriented, and explicitly designed to get usage conditions expected under the circumstances. It is proposed to provide application designers “write once, run anyplace” (WORA), implying that the aggregated Java code can continue executing all phases that support Java without the prerequisite for recompilation. Any equipment or programming condition where a program runs is known as a platform. Since Java includes a runtime environment (JRE) and API, it is called a platform. In this article, we will cover the different versions of Java with their functionality.

What is Java?
- Java is Object-Oriented: Java can be successfully improved since it relies upon the Object model.
- Platform Independent: Not at all like various other programming languages like C and C++, when Java is assembled, it isn’t arranged into platform explicit machine, rather into platform-independent free byte code. Byte code is distributed over the internet and interpreted by the JVM on whichever stage it is being continued running on.
- Simple: You can easily learn Java if you understand the basic concept of object-oriented programming.
- Secure: With Java’s safe feature, it empowers to create virus-free frameworks. Authentication procedures depend on open key encryption.
- Architecture impartial: The compiler of Java language creates an architecture impartial object, which provides the code that is assembled on numerous processors, with the nearness of Java runtime framework.
- Robust: Java tries to wipe out mistake inclined circumstances by emphasizing fundamentally on compile-time and runtime checking.
- Multithreaded: By using Java’s multithreaded concept, it is conceivable to compose programs that can execute numerous tasks simultaneously. This feature enables the designers to build associated applications that can execute easily.
- Interpreted: Byte code is made an interpretation of on the fly to local machine directions and isn’t put away anyplace. The development procedure is increasingly fast and scientific since connecting is a linking and transparent operation.
- High Performance: By using the utilization of Just-In-Time compilers, Java empowers high-speed execution.
- Distributed: Java is intended for the appropriate condition of the web.
- Dynamic: Java is viewed as more powerful than C or C++ because it is intended to adjust to a developing environment. The programs can convey a broad measure of run-time data that can be utilized to check and resolve gets to objects on run-time.
As indicated by Sun, 3 billion gadgets run Java language. There are numerous gadgets where Java is as of now utilized. Some of them are as per the following:
- Work area Applications, for example, acrobat reader, media player, antivirus, and so on.
- Web Applications, for example, irctc.co.in, and many more.
- Enterprise Applications, for example, banking applications.
- Installed/Embedded System
- Smart Card
- Mechanical autonomy
- Games, and so on.
Types of Java Applications
Below are the different types of java applications:
1. Standalone Application
Independent/Standalone applications are also called as work area applications or window-based applications. These are customary programming that need to be introduced on each machine. Instances of independent applications are Media player, antivirus, and so on. AWT and Swing are utilized in Java for making independent applications.
2. Web Application
An application that keeps running on the server-side and makes a dynamic page is known as a web application. At present, Servlet, JSP, Struts, Spring, Hibernate, JSF, and other technologies are utilized for making web applications in Java.
3. Enterprise Application
An application that is allocated in nature, for example, banking applications and so on, is called undertaking application. It has the advantages of abnormal state security, load adjusting, and grouping. In Java, EJB is utilized for making enterprise applications.
4. Mobile Application
An application that is made for cell phones is known as a mobile application. At present, Android and Java ME are utilized for making mobile applications.
Java is an object-oriented, class-based, simultaneous, verified and universally useful computer programming language. It is a generally utilized robust innovation. It can be utilized by developers to create applications on your computer. Java projects are translated by the Java Virtual Machine (JVM), which keeps running on various platforms. This implies all Java programs are multiplatform and can keep running on various platforms such as Macintosh, Windows, and Unix PCs.
